This study aims to analyze and compare environmental attitudes of interest groups, including visitors, local residents, Buddhist monks, and staff of the Korea National Park Service in Gayasan National Park. To achieve this purpose, five hypotheses were formulated and tested. While three hypotheses were statistically rejected, two were accepted. In every interest group, the environmental attitude level of women was higher than that of men. Local residents particularly showed statistically significant differences in accordance with occupation. The difference in environmental attitude between visitors and local residents was not statistically significant. Finally, the environmental attitude level between interest groups was divided into three groups. The staff of the Korea National Park Service showed the highest level of environmental attitude, followed by Buddhist monks, and a group of visitors and residents recorded the lowest. However, the average level of environmental attitude of every interest group scored above the mid-point of 3. Therefore, it can be concluded that there exists no difference between or conflicts among interest groups related to strengthening conservation and management policies regarding the protection of Gayasan National Park.

This study aims to analyze and compare the environmental attitude level and characteristics of interest groups, including visitors, local residents, and local public servants (Cheongsong-gun), in Juwangsan National Park. A statistical analysis of 418 questionnaires concluded that there was no statistically significant gender difference in the level of environmental attitude between the visitors, local residents, and local public servants. In the case of visitors, no significant difference was found in the level of environmental attitude according to age and occupation, but the level of environmental attitude of local residents showed a significant difference according to age and occupation. In general visitors, local residents, and local public servants all scored above the mid point on average, but no statistically significant difference in environmental attitude was observed between these groups. Therefore, it is concluded that mutual consensus can be derived from these interest groups to strengthen the protection of Juwangsan National Park.

The main purpose of this study was to comprehensively evaluate the local agenda 21 of Daegu City based on the evaluation model and propose important measures to solve its problems and improve the limitations. As a whole, the evaluation result of the local agenda 21 of Daegu City showed very low score, only 151 points out of 500 points and revealed it was below the level in all three domains of making process, designed content, and evaluation of implementation. The making process got only score below the half in all large indicators of understanding, driving, and rationality. This unsystematic and irrational process inevitably resulted in ambiguous and proclamatory content mainly expressing willingness to do. This fact means that the local agenda 21 of Daegu City has not served as the comprehensive local environmental plan containing visions, policies, ends and means. It did not suggest evaluation system and institutionalization of evaluation. These results of evaluation suggested that the existing local agenda 21 of Daegu City was neither useful nor effective and thus the totally new local agenda 21 should be prepared. Finally, important measures in making process, designed content and evaluation of implementation were proposed for the remaking.

This study was conducted to develop the evaluation model which can analyse local agenda 21 comprehensively and systematically from the making process to the designed contents. The evaluation model was devised through the theoretical review of local agenda 21 and designing the evaluation system composed of evaluation domains, related indicators and scales. The evaluation system was carefully constructed based on planning theories and the discussion and agreement of specialists regarding local agenda 21. This model has three evaluation domains of process, content, and evaluation of implementation with different weighting values. Each domain contains large indicators, medium indicators and small indicators. Each indicator has different weighting value according to its importance. Basically, each small indicator was scored by 3 or 5 point scale. This evaluation system can not only analyse local agenda 21 quantitatively, but also find out good points, problems, and limits of various phases of planning and implementing local agenda 21.

This study was conducted to find and explain characteristics of diverse social groups' attitudes toward nuclear power plant. 7 hypotheses were constructed and statistically tested. In order to test 7 hypotheses, both Nuclear Energy Attitude Scale and Environmental Attitude Scale were distributed and field surveyed on 839 respondents representing a diverse range of subject groups. The results showed that 6 hypotheses were statistically accepted while 1 hypothesis statistically rejected. Contrary to the first hypothesis, this test found that people in close proximity to the nuclear power plant had more positive attitudes toward nuclear power than those living in distance from the nuclear power plant. Males had more positive nuclear energy attitudes than females. Academic backgrounds were not related to nuclear energy attitudes. Environmental attitudes showed negative relationship with nuclear energy attitudes. While anti-nuclear citizen action groups had the most negative attitudes, nuclear power plant workers had the most positive attitudes among responding groups. Finally, university students majoring in nuclear engineering had more positive attitudes than those of religious studies.

In order to know the effect of autoclaving on the heavy metal removal using chitosan, lead removal capacities and removal rates by various chitosans in aqueous solution were compared according to the various autoclaving time. The lead removal efficiencies and removal rates by the autoclaved chitosan were found to be on the order of 15 min(98%) 〉10 min(95%) 〉30 min(83%) 〉5 min(53%) 〉60 min(47%) 〉0 min(22%) chitosan. The molecular weight of chitosan was decreased by the increase of autoclaving time. Therefore, the heavy metal removal capacity was not well correlated to the molecular weight. Langmuir isotherm was well fitted to experimental results of equilibrium adsorption on chitosan. In order to examine the process of lead removal by the autoclaved chitosan, TEMs, SEMs and FT-IR analyses were used. The surface of autoclaved chitosan was much more porous and the lead removal was mainly occurred on the surface of chitosan. The structure of autoclaved chitosan was same as that of controlled chitosan.

This study was conducted to design long and short forms of reliable and valid Likert-type scales to measure environmental attitudes of Korean junior high school students. 8 tests were applied to the construction of a 32-item long form and 8-item short form of the scale. Two scales were field tested on 469 respondents consisting of male and female students in urban and rural areas and students participating in environmental programs. The 32-item scale was revealed to be highly reliable, content and construct valid. Reliability and homogeneity of this scale were evidenced by 0.92 coefficient alpha and positive interitem correlation values ranging from 0.10 to 0.52. Factor analysis and known-group comparison showed the sufficient validity of long form scale. Reliability and validity of short form scale were also evidenced by good results of 8 test analyses. The long and short forms were strongly correlated, r-value of 0.90. Consequently, both long form and short form scales were evidenced very reliable and valid in measuring environmental attitudes of junior high school students in Korea. They can be useful for a variety of survey conditions and constraints and testing environmental attitude.

The purpose of this study was to design a reliable and valid Likert-type scale to measure nuclear energy attitudes of various groups. 8 tests were applied to the construction of a 26-item long form, a 12-item middle form, and a 6-item short form of the scale. Three scales were field tested on 760 respondents representing a diverse range of subjects. The 26-item scale appeared to be reliable, content valid and construct valid. Scale reliability and homogeneity were evidenced by 0.95 coefficient alpha and positive interitem correlations ranging from 0.18 to 0.74. The results of factor analysis and known-groups comparison revealed that this scale had high validity. Reliability of the middle form and short form were evidenced by coefficient alpha of 0.92 and 0.90 respectively. The long and middle forms were strongly correlated, r-value of 0.98 and the long and short forms were also highly correlated, r-value of 0.93. Consequently, long form, middle form and short form scales were evidenced very reliable and valid in measuring nuclear energy attitudes of various groups in general. They can be used for a variety of purpose of measuring and testing nuclear energy attitude.

This study was conducted to develop the questionnaire for the measurement of environmental attitudes and test its reliability and validity. Development and validation of the 46 survey items that measure environmental attitudes were described. The total of 3 surveys were conducted and the total of 510 persons including diverse sample groups were questionnaired. The SAS PC+ package program was used in both the reliability analysis and the validity analysis of surveyed data. Results revealed the very high reliability and the high validity of the questionnaire. The reliability of the finalized questionnaire was increased to the level of Cronbach-α 0.92 after the repeated reliability analyses and revisions of the firstly and secondly designed questionnaires. The validity of our questionnaire was sufficiently affirmed through the use and application of factor analysis and known-groups technique.

The purpose of this study is to suggest the estimation model of `amenity environment` by Perceived Environmental Quality Index(PEQI) model. A questionnaire survey was carried out for the study area of Taegu-Kyungbuk region. Sampling size was 838(427 of Taegu and 411 of Kyungbuk) residents by stratified sampling of each region`s(7 Gu for Taegu, 7 Cities & Gun for Kyungbuk) population. The survey was done during Sep. to Nov. of 1996. The suggested model was composed of four estimation categories and 16 indicators. The four categories were `Cleanness & Quietness`, `Naturalness & Harmony`, `Beauty & Comfort` and `Environmental Conservation Efforts`. And each category has several individual indicators. The weighted means of satisfaction were different by each region. Suseong-gu, Dalseogu, Joong-gu(Taegu), Kimcheon, Andong, and Cheondo(Kyungbuk) showed high environmental satisfaction, but Dong-gu, Seo-gu(taegu), Youngcheon, and Pohang(Kyungbuk) showed lower environmental satisfaction. By Analytic Hierarchy Process(AHP) of weighting values for each categorirs, `Environmental Conservation Efforts` was estimated as the most important(value of 0.367), and `Naturalness & Harmony`(0.242), `Clenness & Quietness`(0.225), and `Beauty & Comfort`(0.166) were important respectively. Total PEQI`s were estimated as 48.0 for Taegu, and 53.3 for Kyungbuk. PEQI`s for each regions were between 46.2(Dong-gu) and 59.9(Kimcheon). The validity of the suggested model was verified by factor analysis. The four factors were identified as the same categories and indicators. Finally, The LISREL+7 model was suggested as estimation model of `Amenity Environment` for Taegu-Kyungbuk region.

Volatile organic compounds(VOCs) are of concern for their potential chronic toxicity, their suspected role in the formation of smog, and their suspected role in destruction of stratospheric ozone. Present study evaluated the exposures to selected VOCs in three microenvironments: 2 chlorinated and 5 aromatic VOCs in the indoor and outdoor air, and 5 aromatic VOCs in the breathing zone air of gas-service station attendants. With permissible Quality Assurance and Quality Control performances VOC concentrations were measured 1) to be higher in indoor air than in outdoor air, 2) to be higher in two Taegu residential areas than in a residential area of Hayang, and 3) to be higher in the nighttime than in the daytime. Among five aromatics, Benzene and Toluene were two most highly measured VOCs in breathing zone air of service station attendants. Based on the sum of VOC concentrations, the VOC exposure during refueling was estimated to be about 10% of indoor and outdoor exposures. For Benzene only, the exposure during refueling was estimated to cause about 52% of indoor and outdoor exposure. The time used to calculate the exposures was 2 minutes for refueling and 24 hours for indoor and outdoor exposures.

This paper evaluates the historical development of national park policy and administration in Japan from the perspective of achieving sustainable development in nationally important ecological areas. Contrary to the widely held belief, the national park system in Japan has been unsuccessful in balancing conservation and development. The fundamental reasons for its failure are as follows: the Japan`s national park system has been largely founded and developed based on economic grounds and held sway by economic development policy; the policy and administrative coordination between government units concerning conservation and development has not been carried out; public participation and environmental groups` involvement in the decision making have been extremely limited; national parks have been perceived in the public image not as distinctive national heritage but as finest and popular tourist sites; and the dominant interest of tourism and recreational development has prevailed over conservation interest. Japan`s unsuccessful experience and lessons imply that there is urgent need to drastically reform our national park system, largely founded on the Japanese model, in order to save our last national environmental heritage.

Recycling is receiving increasing social attention today as our nation begins to grapple with the significant problems caused by huge amount of municipal solid waste. The topic of recycling is not simple but extremely complicated. This study attempts to provide basic data and policy options for expanding and improving separated collection and recycling in public residential areas, through three case study of apartment housing areas in Taegu Metropolitan City. The main results of this study are summarized as follows. For the significant period of time, all three case areas had in common the extreme difficulty in establishing and operating the system of connecting public participation, collection and storage, transportation, and actual recycling of materials because of a variety of problems involved in this process. Both amounts of and prices for collected materials fluctuated considerably over time mainly due to monthly changes in recyclable home materials and the dynamic nature of recycling markets. Public questionnaire survey revealed the very high level of participation in separated collection, not only because almost all respondents well understood the necessity and importance of recycling, but because they also knew how to do separated collection. But overall activities were rated low and most respondents suggested the enlargement of public participation, the improvement of collection and storage facilities, and collection transportation networks. In particular, most respondents had little experience of using recycled products and used mainly reproduced soap and bathroom tissue. Furthermore, they were considerably unsatisfied with low variety and quality of recycled products, their high prices and low availability in the market. Finally potential policy options and activities for improving separated collection and recycling are suggested.
